Clinical Studies

Highest Reported Survival for All Rhythms

Among the large prospective clinical trials that have been published using an automated CPR device, the AutoPulse® Resuscitation System has achieved the highest survival rate. In the CIRC (Circulation Improving Resuscitation Care) trial, the overall survival-to-discharge rate was 10.2%—among the highest ever achieved in an out-of-hospital cardiac arrest (OHCA) trial.1 The PARAMEDIC trial, which used a piston-driven mechanical CPR device, had a 30-day survival rate of just 6.6%.2

Enhanced Circulation with Unmatched Impact on ROSC

Multiple comparative studies have demonstrated improved vital signs because the AutoPulse drives superior blood flow, resulting in coronary perfusion pressure levels 33% higher than those of sternal compressions, positively impacting return of spontaneous circulation (ROSC) and survival. Furthermore, while piston-driven sternal CPR devices have shown no benefit in improving ROSC rates when compared to manual CPR,3 the AutoPulse has increased ROSC rates in numerous studies.4-9

Multiple trials confirm the AutoPulse is superior to manual CPR when it comes to increasing a patient’s odds of achieving ROSC.
